The cyclopædia of anatomy and physiology cyclopdiaofana03todd Year: 1847 The limbs of a frog prepared according to Gal- vani's method, the nerve of the galvanoscopic leg being laid across the muscles of one thigh. When these muscles are thrown into contraction by any means, mechanical or galvanic, those of the leg con- tract at the same moment. Fig. 393c The limbs of a frog prepared after Galvani's fashion. In another frog the galvanoscopic leg is prepared, but the sciatic nerve is left in connection with the lumbar plexus and the spinal cord. If this nerve be laid across the thighs of the frog and the limbs be made to contract, contractions will be simultaneously excited in the galvanoscopic leg and also in the other one. It is plain that while the contractions in the galvanoscopic leg are excited by the direct stimulation of the sciatic nerve, those in the other leg are excited through the excitation of the spinal cord by the sensitive fibres of the same sciatic nerve.
